BaseMemoryLib:
Correct wrong ASSERT()s on SetMem16(), SetMem32(), SetMem64()
HobLib:
Add Missing ASSERT()s for BuildGuidHobData() since CopyMem() now allow zero source buffer with length > 0.
BasePrintLib
Add ASSERT()s to check NULL buffer and NULL format.
PostCodeLib
Add 3 instances of PostCodeLib and introduce new Pcd for post code property mask.
